SpongeBob takes Patrick to this carnival in this episode to surprise him with the gift he and Sandy made for him: a Chocolate Balloon. However, a group of Chocolate Eating Scallops start going after the balloon and Sandy has to delay her arrival. As a result, Patrick's Valentine's Day gift is limited to a handshake from SpongeBob. Jealous from all the gifts SpongeBob gave to various people, Patrick goes on a rampage at the carnival and performs several villainous acts like ripping the costume off a guy dressed in a heart outfit, attempting to demolish a ride, and snatching a little girl's heart-shaped lollipop and eating it. However, he doesn't cause any serious destruction to its property, and eventually ends his rampage once Sandy arrives with the balloon.
